, 6 Claims. (01.1280-19) The invention relates to portable machines,such for example as small portable power driven liquid pumps, and hasfor one of its objects to provide a simple, effective and relativelyinexpensive skid base or support therefor, whereby the apparatus may beeasily drawn over the ground to position it for use.

A further object of the invention is to provide a base or support of thecharacter indicated which may be quickly and inexpensively constructed,principally from sheet material, and to which the pump or otherapparatus may be readily attached and detached. 7

Still further objects of the invention are to pro vide a sheet metalbase .or support having reinforcing beads pressed or stamped therein,which also serve as ground-engaging runners; to provide a base orsupport which may, and preferably does, have an upturned forward end forfacilitating its movement over the ground; and which is provided withmeans wherebya cord or rope such as is commonly supplied for startingthe small internal combustion motors of the machines may be readilyattached to and detached from the base and thereby also serve as a draftmeans for the apparatus.

With the above and other objects in View, which will be apparent fromthe following description and claims, the invention consists in thenovel details of construction and combinations of parts more fullyhereinafter disclosed and particularly pointed out in the said claims.

Referring to the accompanying drawing forming a part of thisspecification, in which like reference characters designate like partsin all the views:

Figure 1 is a perspective View of a portable centrifugal liquid pump,mounted upon a skid base or support constructed in accordance with thepresent invention;

Fig. 2 is a plan view of a as is shown in Fig. 1;

Fig. 3 is a side elevational view of the parts shown in Fig. 2; and

Fig. 4 is a transverse sectional view, taken on the plane indicated bythe line 4-4 in Fig. 3.

The pump illustrated in Fig. 1 as representative of the apparatus towhich the skid base of the invention is applicable is a well knowncommercial form of portable internal combustion engine drivenself-priming centrifugal liquid pump, in which the pump 10 is providedwith an intake connection H, a discharge connection l2 and an impeller(not shown) which is connected to and driven by the crank shaft of aninternal combase or support such bustion engine l3, the crank case [4 ofwhich is provided at opposite sides with lugsor feet l5 by means ofwhich it may be secured to a support.

The present skid base or traversing support for such an apparatuscomprises a sheet or plate l6 of metal or other suitable material,having a flat generally rectangular body portion I! which merges into atapering forward portion l8 which is preferably curved upwardlyapproximately as shown in Figs. 1, 2 and3. A pair of spacedlongitudinally extending downwardly facingvbeads 20 is. pressed, stampedor otherwiseformed in the body portion H, which beads preferablycontinue into the up-turned tapering forward portion [8, in generalparalleling the lateral edges'of. the sheet or plate and meeting at 2 I.These beads not only reinforce the sheet or plate l6 against transversebending, but those portions of them carried by the flat body portion llact as ground-engaging runners and facilitate the movement of theapparatus over the ground surface by reducing the area of contact, aswill be readily understood; and the portions of the beads extending intothe upwardly curved forward end portion l8 tend to maintain its curveand prevent it from straightening out under the influence of pullexerted on the draft means.

Bars orstrips 22 may be secured, as by spot welding, or otherwise, tothe upper surface of the body portion ll, spanning portions of the beads20 as shown, and provided with apertures 23 suitably positioned toreceive the bolts or screws 24 by means of which the feet or lugs l5 ofthe engine crank case may be detachably securedto the skid base.

A draft eye 25 is secured to the forward end of the up-turned portion[8, which eye may be conveniently formed from round rod intosubstantially the shape shown, with rearwardly divergent legs 26 whichare spot welded or otherwise secured to the plate. The knotted end 21 ofa draft cord or rope 28 may be introduced through the broad base portion29 of this eye and then moved forwardly to engage the knots beneath therestricted forward portion of the eye, providing a simple and effectivemeans whereby the draft cord or rope may be readily attached to anddetached from the skid base. As above stated, this draft cord or ropemay conveniently be the cord or rope usually furnishedand employed forstarting the small internal combustion engines oom monly used in thistype of apparatus, and the rope be thus utilized for dual functions.

Pumps of the type illustrated are frequently used under conditionswherein they of necessity struction as well as the precise arrangementof parts without departing from the spirit of the invention andtherefore it isnot' wishedto be limited to the above disclosure exceptas may be required by the claims.

What is claimed is:

l. A portable pump having a skid base or support comprising a plate ofsheet material having a substantially flat body portion andan upwardlyturned forward end portion, the-under surface of at least said bodyportion being provided 'with a-plurality of spaced beads for'reinforcingsaid portion against bending, said beads also constituting runnersengageable with the surface of'the ground to facilitate movement of theapparatus thereover; and. means for connecting a draftmember to saidbase.

2 A portable pump having a skid base or support comprising a plate ofsheetmaterial'having a substantially flat body portion and an upwardlycurved forward end portion, the under surface of said plate beingprovided with a plurality of spaced. longitudinally extending beads forreinforcing both. of said portions against transverse bending, theportions of said beads located on the body portion of the plate alsoconstituting runners engageable with the surface of the ground tofacilitate traverse of the apparatus thereover; and means for connectinga draftmember tothe forward end portion of said base.

3. A portable power driven pump having a skid base or support comprisinga sheet of material having a substantially flat body portion and anupwardly curved tapering forward end portion, said sheet having adownwardly pressed bead substantially paralleling the lateral edges ofboth of said portions to reinforce them against transverse bending, theportions of said beads located on the said body portion alsoconstituting runners engageable with the surface of the ground tofacilitate movement of the apparatus thereover; means carried by saidbody portion for the detachable securement of the pump apparatusthereto; and means for the readily detachable connection of a draftmember to the forward end portion of said base.

4. As an article of manufacture, a skid base or support for a portablemachine, comprising a plate of sheet material having a substantiallyflat body portion and an up-turned end portion, said plate having aplurality of longitudinal beads projecting from its lower surface tostrengthen both of said portions against transversevbending, the partsof the beads located on the body portion also constituting runners, forengagement with the surface of theground to facilitate-movement of theapparatus thereover; and means for connecting a draft member to saidbase.

5. A skid base or support according to claim 4, wherein the draft memberconnecting means comprises an eye carried by the up-turned end portion,,andprovided with an aperture having-a narrow portion and a broaderportion, through the latter of which a knotted end of a draft cord orrope maybe passedand then moved to engage the knot with the narrowerportion.

6. A skidbase or support according to claim 4, wherein the upper face ofthe body portion of the plate isprovided with members rigidly securedthereon to which the portablemachine may be fastened.
